In more than 25 years, Willems Industriële Producties B.V. has developed a particular specialism and expertise in the application of high frequency (HF) technique. This technique is used for welding various plastic products, or textile products which contain plastic.
Willems Industriële Producties B.V. delivers both new and used HF welding machines, overhauls your existing HF welding machines (retrofitting) and provides professional service and advice in the field of high frequency (HF) technique.
On this page you will find more information about the principle of HF welding technology, the benefits compared to other plastic welding techniques and the various applications.
You will also find extensive information on our delivery programme, about kinds of machines and their applications, about custom made machines, our stock of used machines, our service for all HF brand welding machines, our stock of spare parts, radiation measurements, our extensive facilities for your prototyping and pilot series, etc..
High frequency welding technique is based on dielectric heating of the material to be welded. Dielectric heating occurs when a material with polar molecules, which is a poor conductor of electricity, is inserted into a variable electrical field. Polar molecules, whose positive and...
Advantages of high frequency welding technology to other joining processes: very even and very fast melting process, accurate control of the melting process (dosage, duration and position) possible. The great advantage of high frequency welding is speed. The materials to be welded are...
High frequency welding machines can be used for welding various products, such as: Car upholstery Orthopaedic bandages Blister packaging Inflatables Tarpaulins Banners Tents and tent canvasses Car mats Water beds Infusion and blood bags Cushions Rain gear Air filters Life jackets Comfort Seat...
